LWN.net founder and kernel contributor Jonathan Corbet offered an analysis of the code contributed to the Linux kernel between December 24 2008 and January 10 2010. 18% of contributions were made without a specific corporate affiliation, 7% weren't classified, and 75% were from people working for specific companies in roles where developing that code was a major requirement. "75% of the code comes from people paid to do it," Corbet said.

If you follow that line of reasoning, everything has a "tax" for some other corporation or technology. You are basically pointing out the utterly uninteresting fact that the money you give to pay for something is in turn spent on paying other people to do things.
